Rose plant

ABSTRACT

A new miniature rose variety of bright yellow coloring borne singly and in large sprays.

The present invention relates to a new and distinct variety of roseplant of the miniature rose class, which was originated by my crossingas seed parent the rose known as "Rise N' Shine" and the deep yellowrose known as "Kiskadee" as pollen parent. The generic name of thisvariety is "Savacent" and the commercial appellation is "Center Gold".

Among the novel characteristics possessed by this new variety whichdistinguish it from its parents and all other varieties of which I amaware are high centered, heavily petaled flowers of bright yellowcoloring. Flowers, which are borne singly and in large sprays, areattractively contrasted against attractive green foliage which istextured like the rose "Arthur Bell". Asexual reproduction by budding ofthe new variety as performed in Essex County, Mass., shows that theforegoing and other distinguishing characteristics come true to form andare established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetativegrowth and flowers of the new variety in different stages of developmentand as depicted in color as nearly true as it is reasonably possible tomake the same in a color illustration of this character.

The following is a detailed description of my new variety, with colorterminology in accordance with the Royal Horticultural Society ColourChart (RHSCC). The terminology used in color description herein refersto plate numbers in the aforementioned color chart, e.g., "15B" is plate15B of the Royal Horticultural Society Colour Chart.

Parentage: Seedling.

Seed parent.--"Rise N' Shine".

Pollen parent.--"Kiskadee".

Class: Miniature.

The following observations are made of specimens grown outdoors in EssexCounty, Mass. during the month of October.

1. FLOWER

Blooming habit: Fast recurrent.

A. Bud:

(1) Size.--Medium.

(2) Form.--Pointed, ovate.

(3) Color.--When sepals first divide -- 15B.

(4) Sepals.--Normal slightly foliated.

(5) Peduncle.--Length -- about 1 inch. Aspect -- Straight. Strength --Erect. Color -- 144D.

B. Bloom:

(1) Size.--Average size when fully expanded -- about 11/2 inches.

(2) Borne.--Singly and in sprays of 3 to 12 blooms.

(3) Form.--High centered at first reflexing as bloom matures.

(4) Petalage.--Number of petals under normal conditions -- about 55 to65.

(5) Color.--Yellow buds open into attractive high centered brightyellow, near 15B, flowers with inner petals indicating some blendingwith 22C in the very deep center. Outer petals are near 15B lighteningto 15D toward petal edges with 11D at point of petal attachment. Thegeneral tonality from a distance is golden yellow when flowers are halfopen. As blooms age flower color lightens considerably. As blossoms openfully, color pales considerably. Outer petals quill and turn pure whiteand as blossom ages further, the entire blossom becomes pure white. Allpetals are held and recurl to ball-like form of pure white with nodiscoloration. An unusual characteristic of this variety is that theplant occasionally develops a near white bloom sometimes even on thesame cane with other normal yellow colored flowers. This characteristicis somewhat more prevalent with an increase in fertilization level.

C. Petals:

(1) Texture.--Thick.

(2) Appearance.--Velvety with veining.

(3) Form.--Fan shaped quilling to points.

(4) Arrangement.--Regularly arranged, shingle-like.

(5) Petaloids in center.--Normal.

(6) Persistence.--Drop off cleanly.

(7) Fragrance.--Sweet, spicy.

(8) Lasting quality.--Long lasting on plant and when cut.

2. REPRODUCTIVE ORGANS

A. Stamens, filaments and anthers:

(1) Arrangement.--Irregular, sparse.

(2) Color.--Light yellow.

B. Pollen:

Color.--Light yellow.

C. Styles: Bunched, uneven length.

D. Stigmas:

Color.--Light yellow green.

E. Hips:

Shape.--Globular.

Size.--About 3/4 inch diameter.

Color.--Orange, about 33A.

Do seeds protrude?--No.

3. PLANT

A. Form: Upright, compact.

B. Growth: Very vigorous.

Height attained.--About 15 to 18 inches.

C. Foliage: Compound 5 to 7 leaflets.

(1) Size.--Medium.

(2) Quantity.--Abundant, profuse.

(3) Color.--Foliage: Dark green.

(4) Shape.--Oval.

(5) Texture.--Glossy and textured like the rose "Arthur Bell" and underside is matte.

(6) Edge.--Serrate.

(7) Serration.--Medium.

(8) Leaf stem.--Color -- green.

(9) Stipules.--Medium.

(10) Resistance to disease.--Blackspot -- Average. Mildew -- Average.Rust -- Average.

D. Wood:

(1) New wood.--Color -- Near 144A. Bark -- Smooth.

(2) Old wood.--Color -- Near 191A. Bark -- Rough.

E. Thorns:

(1) Thorns.--Quantity (main stalk): Average. On laterals from stalk --Average. Form -- Long thin pointed angled slightly downward. Length --Medium. Color -- Near 145C. Position -- Irregular.

(2) Prickles.--None.

F. Winter hardiness: Average.

I claim:
 1. A new and distinct variety of rose plant of the miniatureclass, substantially as shown and described, characterized particularlyby high centered, bright yellow blooms of heavy petallage borne singlyand in large sprays (3 to 12 blooms).
